Abstract

The article provides the study of electrodynamic and electronic parameters of a capacitively loaded double-gap resonator for a multibeam klystron. The resonator’s design features the mushroom-shaped structure and extra rods along the resonator perimeter. Simulation results were obtained with different sizes of the resonator structure elements.
